It is among the objects of my invention to provide improved power operated cleaning apparatus.

Other objects will appear hereinafter. The invention consists in the novel combination and' arrangements of parts to be hereinafter described and claimed.

The invention will be best understood by., reference to the accompanying drawing,

showing the preferred form of construction and in which:

Fig. 1 is an elevational view depicting a preferred form of construction for my invention showing one of my cleaning members secured to the operating portion of my device; Y y

Fig. 2 is a planv view -of myimproved cleaning member; v v

Fig. 3 is a sectional vievsT taken substantially on the line 3-3 on Fig. 2;

Fig. 4; is a perspective detail view. In the accompanying drawing wherein I have illustrated a preferred form of construction for my invention 10indicates an electric motor which may be of any approved form but which includes in the present instance a speed varying mechanism which is operated by the handle l1 that protrudes through a slot 12 formed in the housing of the motor 10. While this is thearrangement shown it is to be understood that any desired electricmotor might be provided without departing from the purview of my invention. A

In the present instance a, band 13 is'shown as being disposed around the motor `l() and f serves to connect the motor 10 to the handle 14.'- In the present instance the current carrying conductors 15 are directed through the handle 14 to the motor 10.

Extending outfrom one end of the frame j of the motor 10 is Van elongated sleeve i161 through which the shaft 1710i the motor ex- 750 tends. The above described arrangements shaft will tend to more securely'retain the i929. serial 110.356.854.'Y

are the preferable form ofconstruction for my invention but it is tobe understood that this specific arrangementmight be departed from without departing.- fromthe` pur-view 1 ofmy invention. F56

Vthe present inst-ance I show one form of my 4improved cleaning mechanisms in association with the mechanisms Vheretofore described and this improved cleaning mechr anism is.indicatedgenerallyfby 18.v VBy re- 00 ferringto Fig. 3 4it may be seen; that the cleaning member18 includesa substantiallyV cylindrical shaped member. 19 that comprises a relatively flat portion 2 0 around whicha proJecting. rim 421 isprovided. To-substan- 651 ltially the midpoint of the section-20 ofthe member 19 a threadedV stud 22 is secured ,and the threaded stud 22'isintended to be screw threadedly itted into an opening formed in the` motor shaft 17 and, the lead of the 7o threads on the stud 22 is preferably inthe direction ofrotation ofthe shaft 17in order thatthe rotative movement imparted to the stud'22, in position. A

In Vthe preferred -formfof i shown a suitable substantially circular block '28k Sis, provided which; has afgroove 29' `formed therein adjacent the periphcrvtherelof and the groove 29 Aelitendsgintoblock 28 so Vfrom one facethereof. Af covering-of textiley material ,30 is disposed over the face of the bloclr28 oppositev that into whichlthe groovejextends and this cloth l30 is extended `outxavardly overthe sides-of the blockand l .inwardly tothe groove `29 so as 'to extend .across the lower face, thereof.` 'InV this .in-ff.

A:ring'22 has openings thereinthrough yvvhichtlle, studs 31-lnaygextend in 4 orderthat the ring 32 may be disposed over the section, ofjcloth Vatthe bottom of the groove 29. Wing nuts 133 are Varranged on the` studs'. 31.` `95 :to retainthering 32,.-in position; I 1

The. member19 embodies a `substantially cup-shaped/membel 23whichis preferably` formed from flexible material. A ring of yielding material indicated by 24 Vis dis- :100'` posed interiorly of the rim 21. The ends holding member portion retain the latter of theV ring 24 overlap each other and a slot within said ring, and means for rotating said 25 is a. stud bolt 26a threaded into rim 21 projects through the slot 25. Wing heads 27 are.provided on bolts 26 to force the same into engagement with the ring 24 and the -latter into engagement with the portion Vof .cloth 30 that is disposed between block 28 and ring 24. The cup-shaped member 23 engages an inwardly disposed surface of the block 28 and by'forcing the block so as to slightly depress the cup-shaped member 23 and then releasing the same a partialY vacuum may be defined in the cup-shaped Vmember 23 which is sealedv by the engagement of the surface of the block 28 with this cup-shapedY member 23. This partial vacuum in cooperation with the yielding ring 24 serves to very effectively retain the block 28 in the member 19 and in this manner the block 28 is connected to the member 19 so that it will be rotated with said member 19 when the Stud 22 isrconnected to the Shaft 17.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this iscapable of variation and modification, without departr ingjfrom the spirit of the invention. I, therefore, do not wish to be limited to the precise details of constructionset forth, but desire to avail myself of such variations and modifications as` come Within the scope of the appended claims.

Having thus described my invention what I claimasy new anddesire to protect by Letters Patent is: Y

1. A device of the character described comprising a member including a plate and a rim around and opstanding from theplate, a member adapted to be disposed Within the rim, means for retaining said second-named member on said first-named member, a resilient split fring disposed within the rim between the rimVv and the second-named member, a cleaning member including a portion extended across one side of said secondnamed member and includinga portion dis-V posed between the ring and the secondnamed member, means for contracting the ring to bind the saidYsecond-named portion of the cleaning member against thejsecondnamed member and means to rotate said dev1ce. Y

2. A device of the character described;

provided in one of the ends while device.
